About: How coal is formed - Practically demonstration!
Thank you sir...it was very clear and useful.
AMAZING information but your voice is very low
Wonderful video. You are a pure gem in teaching geography. No one can explain in such a lucid manner except you. Cheers to joy of learning.
ive been finding black rocks near my house that share alot of similar qualities of those in the video, i feel it is kinda wierd on how ive been picking them all up and finding more later on in the area,
Now I understand that I work in factory in boiling machine and I thought hard to ignite because of wet coal (got drenched from raining) and I noticed that has difference of coal I saw like shiny one that u can crush it by stumping on it and hard one has very dark but not shiny that's very hard so I end up using hammer to crush it.
Thanks you help me in school
